A Succasunna woman has been charged with attempted murder after mixing antifreeze with orange juice she gave her grandmother, according to a joint press release from Morris County Prosecutor Fredric Knapp and Roxbury Police Chief Marc Palanchi.

Elise Conroy, 26, was charged with the attempted murder of her grandmother, identified in the release at “L.E.,” 84, also of Succasunna, the Prosecutor’s Office said.

Conroy was charged Saturday morning with the first-degree crime, related to an ongoing investigation into her attempt to poison her grandmother with liquid antifreeze, the Prosecutor’s Office said.

Conroy allegedly purchased liquid antifreeze in late July with the intent to poison her grandmother, whom she lived with in Succasunna, the Prosecutor’s Office said.

Conroy then allegedly poured the antifreeze into juice and gave the juice to her grandmother, the Prosecutor’s Office said.

The grandmother suspected something was wrong and reported it, according to officials.

While she ingested some antifreeze, she is in OK condition, not injured or hospitalized as of Saturday afternoon, officials said.

The attempted murder charge was authorized by Municipal Court Judge Ira Cohen Saturday, after which Conroy was remanded to the Morris County Correctional Facility pending a future court appearance, the Prosecutor’s Office said.

At the time of her arrest, Conroy was employed at a vet clinic.

Conroy also has a profile set up on the babysitting website Sittercity, on which it says she is “willing to provide sick care.”

The profile also mentions she graduated from Roxbury High School in 2010 and volunteered at Celebrate the Children, a Denville day camp, between the ages 11 and 16.

Members of the Roxbury Police Department, the Morris County Prosecutor’s Office Major Crimes Unit, and the Morris County Sheriff’s Office Criminal Investigation Section contributed to the investigation.

Anyone with information about the case is asked to call the Roxbury Police Department at 973-448-2100 or the Morris County Prosecutor’s Office Major Crimes Unit at 973-285-6200.
